Specification of Letters Patent; t t June 3, 1 5.

Application filed July 22, 1911. Serial No. 689,880.

To all/whom it may concern Be it known that I, GLENN H. Bonus, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and usefullmprovements in Lock-Hangers for Trolley-Wires, of which the following is a specification.

. This invention relates to insulated supporters for electric or other wires, and the principal object of the invention is to provide a supporter or hanger of simple and improved construction and arrangement, which will be effective-and efficient in operation.

Another object of the invention is to provide a tight joint between'the hanger and any article to be suspended therefrom, when the article to be suspended is placed in any desired angular position with respect to the hanger.

For the attainment of these ends and the accomplishment of other new and useful objects, as will appear, this invention consists in the features of novelty in the construction, combination and arrangement of the several parts generally shown in the accompanying drawing and described in the specification, but more particularly pointed out in the appended claims.

In the accompanying drawing Figure 1 is a cross sectional view of my improved hanger showing the parts in their assembled positions; Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1 Fig. 3 is a perspective view of the stud; Fig. 4 is a detail cross sectional view of the cupm'ember; Fig. 5 is a cross sectional view on the line 5-5 of 1; Fig. 6 is a top view showing flattened edges of a member secured in the hanger. y a

. Itis found in practice that in securing trolleyjwires and the like to hangers, the

- member securedto the hanger is frequently brought up tight when secured thereto by a threaded connection at an angle other than the desired angle. In other words, the angle at which thejoint between the twomembers actually becomes tight isvery different than the desired angle, and to turn the member I secured to the hanger to the desired position it must eitherbe' backed off 'or screwed tighten the latter operation frequently re Bu1tmg;. n.s r PP ng.-t r d of one or both of the members. If the. member is backed off a space' remains between the two,

' about the hanger at any desired, angular position with respect to the axis of the stud, at the same time drawing the member tightly against the hangerand holding it securely in the adjusted position.

Referrin now more particularly to the accompanying drawing, a hanger shell 11 is formed with projecting ears 12, by means of which the hanger is secured in any desired or suitable position. The hanger shell is preferably circular in form, and may be made of an suitable material, and is usually of metal. nside of the shell, and at a distance from the open edge thereof, is an annular projection 13, which leaves an internal opening and forms a partially closed chamber therein. The inside of the edge is also formed with a projection 14. TlllS projection 14 and the annular rojection 13 are adapted to assist in retaining the insulation within the hanger shell. A cup member 15 is formed with an opening 16 in the bottom thereof, and with straight cylindrical sides. Intermediate of the ends thereof and on the inside of said member is a projection 17 in the form of a segment of a circle, which presents a flat face portion. Asecond member 18 is formed at one end, with a beveled or cone-shaped portion 19, the base of the cone being prewithin the cup member 15 until it strikes the projection 17. The sides of the cup member 15 are then swaged about the coneshaped portion, and the two members are secured rigidly together. Before the member.

18 is inserted in the member 15, a stud 21 and a spring or spring washer 22 is inserted in the cup member. The threaded end of the stud protrudes from 'the'end of the cup member and thehead is formed with a fiat portion 23, which is adapted to engage but that it may be moved through a limited distance in a direction longitudinally of its axis, being pressed, however, by the spring washer 22 which maintains a yielding pres sure on the stud when articles are threaded upon it and brought to bear against the cup member 15. From this it is evident also that a member threaded upon the stud may be adjusted at any angular position thereupon in a plane transverse to the stud, and held firmly but releasably in the position by means of the spring washer 22.

The members 15 and 18 are positioned within the hanger shell and secured therein by means of some suitable insulating material 24, which holds them firmly in place and spaces them from the shell. The lower end of the cup member 15 preferably projects slightly below the lower edge of the hanger shell, and. is provided adjacent the outer edge with projecting rim 25, which is adapted to hold the insulating material more securely in place. The head 20 of member 18 is inserted through the opening formed by the annular projection 13, and after the insulating material has hardened the annular projection 13 holds the member 18 firmly in position by means of the insulation, even though all of the insulation outside of the projecting annular ring has broken away. It will be noticed that the. flattened edges of the head 20 are formed so that the rotation of the member 18 .is prevented.

While I have thus particularly described the preferred construction, combination and arrangement of the several parts which constitute my invention, it is evident that those skilled in the arts to which this relates may make various changes without departing from the spirit and scope of the invention.

What I claim is:

1. In a hanger for trolley wires, the combination with fixed means within the hanger shell having a stop portion, a stud with its head adapted to engage the stop portion of said fixed means toprevent rotation of the stud, and resilient means interposed between the stud and the said fixed means and beneath the head of the stud to press the latter inwardly in the hanger.

' 2. In a hanger for trolley wires, the combination with a fixed member insulated from the hanger shell and formed with a projecting portion, a studhaving its head ,formed with a lateral flattened portion to engage the said projecting portion to prevent the stud from rotating with respect thereto,

the hanger.

and a spring bearing against the under side of the said head and the fixed member operatlve to press the stud yieldingly within 3. In a hanger for trolley wires, the combination with a cup member fixed in the hanger shell and having an inner lateral flattened rejection, a stud having a flattened sur ace on its head adapted to engage the said projection and to stop any rotative movement of the stud with respect thereto,

the threaded end of the stud extending outwardly through the end of the cup member, and a spring bearing against the under side of the said head and the outer end of said cup member to press the stud yieldingly within the hanger.

4. In a hanger for trolley wires, the combination with a fixed cup member, of means to secure the member in the hanger shell, a stud movable longitudinally in the said member, and yielding means interposed between the cup member and the under side of the stud head to press the stud inwardly, the cup member being provided with means to limit the inward movement of the stud.
